Create a custom alias for a RemoteApp in Windows Server 2012 R2

Edit: fixed a typo in the command in step 3

For Windows Server 2012 R2 it’s not possible to change the alias of an existing RemoteApp. However it is possible to set a custom alias when creating a new RemoteApp using PowerShell.  The steps:

1. Unpublish the existing RemoteApp
2. Start PowerShell
3. Issue the following command to publish the new app with your desired alias. Note that folder name is optional. The collection name you can find in Server Manager under Remote Desktop Services -> Collections.

   New-RDRemoteApp -CollectionName "YourCollectionName" -Alias "YourAlias" -DisplayName "YourDisplayName" -FolderName "YourFolderName" -FilePath "C:\path\to\executable.exe"
